BRIDGE-GATE.

SPECIFICATION forming part Of Letters Patent No 519,274, dated May 1, 1894. Applica n fi February 3, 1894. Serial No. 498,957. (No model.)

To all whom it may concern.-

Be it known that we, JOSEPH SEGO and CHARLES FAUOHER, citizens of the United States, residing at Valparaiso, in the county of Porter and State of Indiana, have invented certain new and useful Improvements in Br1dge-Gates; and We do hereby declare the following to be a full, clear, and exact descriptron of theinvention, such as will enable others skilled in the art to which it appertai'ns to make and use the same.

This invention relates to gates for bridges; and 1t consists in the novel construction and comblnation of the parts hereinafter fully descrlbed and claimed, whereby the gates are opened and closed automatically as the bridge 15 closed and opened.

In the drawings: Figure 1 is a plan view of a bridge and one of its approaches, a portion of the planking of the approach being removed to show the gate operating mechanism, and the bridge being shown partly open. Fig. 2 1s a vertical section, taken on the line no a: in Fig. 1.

. Ais a bridge of approved construction turning upon a central pivot a.

B is one of the approaches to the bridge. Only one approach is shown, as the other is exactly the same in construction.

13' 1s the ledge whereon the edge of the bridge rests when the bridge is closed.

The approach is provided with two similar gates O, and similar gate-openin g mechanism.

The gate 0 is mounted upon a vertical shaft 0, and preferably consists of a long portion adapted to project across one half of the roadway, and a short portion adapted to project across the footway.

D is a spring which normally holds the gate closed. The spring shown is a helical spring, and is secured at one end to the shaft 0, and at the other end to the stationary anchor bolt cl, but any other form of spring, or its equivalent, such as a balance weight, may be used, which will accomplish the same purpose.

E is a longitudinal bar provided with a long slot 6; and e is a guide roller, mounted on a pin projecting from the support E, and engaging with the said slot. The guide constrains the ends of the bar to oscillate in opposite directions.

F is an arm secured on the gate shaft 0, and f is a link pivotally connecting the arm F with one end of the bar E. i

F are the pins by which the link fis connected to the said arm and bar.

G is the operating lever pivoted to the stationary support G by the pin 9. One end of the operating lever is pivoted to the opposite end of the bar E from the link f, by the pin and the other end of the operating lever is provided with a roller H journaled on the pin it.

The operation of the device is as follows: When the bridge is being moved in the direction of the arrow in Fig. 1, the side of the bridge strikes the roller H, and turns the operating lever on its pin 9. This movement draws the bar E endwise, and turns the gate shaft one quarter of a revolution, therebyopening the gate. The parts then assume the positions as shown in the lower part of Fig. .1. The bridge may be revolved to the rightor to the left in opening it, and with the same effect upon the gates, because of the slotted bar E wise in the same direction whether the operating lever is moved to the right or to the left.

matic operating device-such as a spring-= normally holding the said gate closed, an arm secured on the gate shaft, the bar E provided with a guide, a pivoted operating lever arranged in the path of the bridge and pivoted to one end of the said bar, and a link pivotally connecting the other end of the said bar with the said arm, substantially as set forth.

2. The combination, with a pivoted bridge; of a gate secured on a vertical shaft, a spring normally holding the said gate closed, an arm secured on the gate shaft, the bar E provided with a long slot and a guide roller, a pivoted operating lever provided with a roller at one end for the bridge to come in contact with,

and having its other end pivoted to the said bar; and a link pivotally connecting the said bar and arm, substantially as set forth.

3. The combination, with a pivoted bridge;

5 of a gate secured on a vertical shaft, the helical spring secured to the said shaft and adapted to close the gate automatically, an arm secured on the gate shaft, the bar E and its guide roller, a pivoted operating lever ar- 10 ranged in the path of the bridge and pivoted
